Imagine a world where scientists can create life from scratch. It sounds like something out of a science fiction movie, right? But this is actually happening today! Scientists are making artificial life, and it’s not as creepy as Frankenstein’s monster. Instead of using body parts and lightning, they use empty cells and DNA from fungi and bacteria to create tiny new life forms.
So, why are scientists doing this? The benefits could be huge! By creating artificial life, scientists can learn more about how life works at a basic level. For example, back in 2008, researchers managed to create a type of bacteria called mycoplasma. They did this by breaking down its DNA into 101 pieces, which they called “cassettes.” Then, they inserted these cassettes into the DNA of other bacteria like E. coli or yeast. This allowed them to create many different combinations of artificial bacteria.
Since then, scientists have made even more progress. At the J. Craig Venter Institute, researchers created a mycoplasma bacterium with just 473 genes. To give you an idea of how small that is, humans have about 25,000 genes! This tiny bacterium helps scientists figure out which genes are essential for life.
With a smaller genome, it’s easier to study the role of each gene. If removing a gene causes the cell to die, scientists know that gene is crucial for survival. Plus, these artificial organisms can reproduce, allowing scientists to make many copies for research.
These techniques could lead to amazing advancements, like new ways to edit genes, develop drugs, or even boost our immune system to fight diseases. However, there are ethical questions about creating artificial life. Some worry about the consequences of altering nature so drastically.
Despite these concerns, understanding the basic building blocks of life could help us tackle big challenges, like Alzheimer’s disease, nutrition, and brain function. The possibilities are endless!

In what seems like the stuff of science fiction, scientists are synthesizing artificial life. But why alter nature? What benefits could there possibly be? Hello, DNA enthusiasts! Lissette here for DNews. Scientists are creating artificial life, which is reminiscent of how Frankenstein assembled his creature, but instead of using random body parts and electricity, they are using empty cells and chromosomes infused with fungal and bacterial life. Instead of creating one monster, they end up with many tiny creations.
The potential benefits of this artificial life can be significant. Geneticists use various processes to construct synthetic life. For example, in a study published in Science in 2008, researchers synthesized a type of bacteria called mycoplasma. They achieved this by breaking down the original genome into 101 pieces, referred to as “cassettes.” To create a new artificial form of the bacteria, they inserted 1 to 4 of these cassettes into a host bacterium’s chromosome, such as E. coli or brewer’s yeast. This process allowed researchers to create many different combinations of artificial bacterial life.
At the time, this was a landmark achievement, but since then, scientists have advanced their work further. Recently, scientists at the J. Craig Venter Institute synthesized a mycoplasma bacterium with an incredibly small genome of just 473 genes. To put that into perspective, a human has about 25,000 genes. While it may seem trivial for researchers to create such a simple organism, this tiny artificial bacterium can provide insights into which genes are considered the building blocks of life.
With a large genome, it’s challenging to understand the role of each individual gene. A small synthesized genome can help scientists isolate specific genes to see their effects. If a cell dies when a particular gene is removed, scientists can conclude that the gene is essential for life. Additionally, because these organisms can self-replicate, scientists can produce many of them for comparison.
Potentially, scientists can use these techniques to manipulate genes or introduce foreign genes into an organism. This raises ethical concerns about the implications of synthesizing artificial life. However, some scientists believe that synthetic bacterial life can have significant benefits, including advancements in gene editing techniques and drug development, and even new ways to utilize our immune system to combat diseases.
Before these advancements can be realized, some questions remain, such as whether the chromosomes in synthesized bacterial cells encompass the full spectrum of genes. There is concern that these basic genomes may not accurately represent the building blocks of our own DNA. Nevertheless, understanding life’s building blocks could lead to breakthroughs in understanding diseases like Alzheimer’s, cellular nutrition, and cognitive abilities—the possibilities are vast.
